WASL

This repo contains source code and other artifacts related to the paper "WASL: Harmonizing Uncoordinated Adaptive Modules in Multi-Tenant Cloud Systems". WASL is a rate-adaptation based technique for runtime cross-layer coordination in multi-tenant clouds to mitigate performance interference arising due to multiple colocated adaptive applications.
